    • erase

      public static void erase(byte[] data)
      Securely erase byte array by overwriting with zeros 通过用零覆盖来安全擦除字节数组

      This method overwrites the entire array with zeros to prevent sensitive data from remaining in memory. The array reference remains valid but all data is zeroed. 此方法用零覆盖整个数组，以防止敏感数据残留在内存中。数组引用保持有效，但所有数据都被清零。

      Parameters:
      data - byte array to erase (can be null)

    • erase

      public static void erase(char[] data)
      Securely erase char array by overwriting with zeros 通过用零覆盖来安全擦除字符数组

      This method is particularly important for erasing passwords and other sensitive character data that should not remain in memory. 此方法对于擦除密码和其他不应保留在内存中的敏感字符数据特别重要。

      Parameters:
      data - char array to erase (can be null)

    • erase

      public static void erase(ByteBuffer buffer)
      Securely erase ByteBuffer by overwriting with zeros 通过用零覆盖来安全擦除ByteBuffer

      This method works with both direct and heap ByteBuffers. The buffer's position and limit are preserved. 此方法适用于直接和堆ByteBuffer。缓冲区的位置和限制被保留。

      Parameters:
      buffer - ByteBuffer to erase (can be null)

    • erase

      public static void erase(int[] data)
      Securely erase int array by overwriting with zeros 通过用零覆盖来安全擦除整数数组
      Parameters:
      data - int array to erase (can be null)

    • erase

      public static void erase(long[] data)
      Securely erase long array by overwriting with zeros 通过用零覆盖来安全擦除长整数数组
      Parameters:
      data - long array to erase (can be null)
